Bitcoin Gets Real DeFi Access as tBTC Goes Live on Sui Network

• Sui Network now supports tBTC minting, enabling Bitcoin holders to access DeFi tools like lending and trading natively.
• The integration leverages threshold cryptography and fast L1 performance, enhancing decentralized Bitcoin utility on Sui.

The Sui network is increasingly confident in challenging DeFi’s dominance in the crypto industry. Starting early July, Bitcoin owners can convert their BTC into tBTC directly on the Sui network. Through the integration of Threshold Network, tBTC is present as a tokenized version of Bitcoin that is fully supported 1:1, without having to go through Ethereum first.

Sui Network Opens the Door for BTC Holders to Join DeFi Effortlessly

The presence of tBTC on Sui is not just a patchwork of features. This is the answer to the long-standing need of BTC users who want to access DeFi without having to burn expensive gas fees or the hassle of bridging assets to various networks. With tBTC that can be requested directly on Sui, users can take advantage of features such as trading, lending and borrowing, and yield farming with a much faster and cheaper experience.

The launch of tBTC on Sui is not just about technical efficiency. It is also about opening the door for the Bitcoin community to participate in the growing ecosystem, without having to move to another blockchain.

The process is also not as complicated as it used to be—thanks to threshold cryptography technology, tBTC’s security does not depend on a single party or custodian. Users can be sure that their BTC is protected, even after being converted to tokens.

And because all of this happens directly on the Sui network, the user experience is much faster. No more chain hopping or dealing with vulnerable asset bridges. In fact, with Sui’s rapidly growing DeFi ecosystem, tBTC’s presence could expand opportunities without having to leave your main wallet.

The early numbers are also quite intriguing. Since February, around 600 BTC—worth over $65 million—have entered the Sui ecosystem. That amount even represents more than 10% of the total value locked (TVL) on the network.

Now that tBTC is officially live, there is a potential for up to $500 million in new liquidity ready to flow in. Not only for speculation, but also as new ammunition for DeFi projects that have been in need of a breath of fresh air from the Bitcoin community.

Building Trust Through Privacy and Security Moves

On the other hand, in May, CNF reported that after the $223 million hack that hit the Cetus Protocol, the Sui team did not sit idly by. Although the attack originated from a loophole in the protocol and not a fault in their chain, Sui still poured $10 million specifically into strengthening the security sector. This step was considered quite strategic so that developer and user trust would be maintained.

In the same month, Sui also launched a new authentication feature called zkAt and zkAt+. This system is designed to secure access to Web3 applications without sacrificing privacy. Users can prove authentication without having to reveal their identity details to validators or anyone else on the network.

And if at any time the access policy needs to be changed? zkAt+ allows that to be done privately. In a world that is increasingly concerned about privacy, this approach could be an important trump card for wider adoption.

On the other hand, Sui’s momentum continued to strengthen throughout June. Nasdaq even filed the 21Shares SUI ETF, which immediately raised the trading volume of the SUI token and sparked a wave of optimism in the market.

At the time of writing, SUI is trading at about $2.87 and has gained around 2.81% in the last 7 days. Its market cap has also exceeded $9.5 billion.
